About These Birds
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
Large Green-pigeon
Large green-pigeon, 35–36 cm, the largest in the genus, with rich green plumage, a large yellow-green bill, and orange-tinged breast in males. Inhabits lowland dipterocarp and peat-swamp forest from southern Thailand and Myanmar through Sumatra, Borneo, and the Malay Peninsula. Frugivore of large forest figs. Vulnerable due to lowland forest loss.
